The absolute best place to learn how to take care of your finish <

I would never sand and oh yeah that's "wet sand" a new car unless the orange peel was awful or it was a "garge or trailer queen". You only have 1/2 the work with a vert. anyway.
my reccomend would be:
#1-clay bar
#2-Meguiars dual action cleaner polish
#3- 2 coats of Meguiars NXT done a day apart and NO water getting on the finish.
#4- wash the baby at least once or twice a week whether it needs it or not. And immeditely wash any birdie poopie, bugs, tree and berry sap off.
